WILLIAM H. BATON, or ems'rnnnen-nnw YORK, AssIenoR ro s'rErnEn SANFORD &

SONS, INC., OF AMSTERDAM, NEW YORK, A CORPORATION OF NEW YORK.

To all'whom it may concern: v I

Be it known that I, WILLIAM H. PATON, a citizen .of. the United, States, residing at Amsterdam,- in the county of Montgomery andfitate of New .York, have invented new and useful Improvements in Presser-Feet, of which the. following is a specification;

This invention relates to an improved presser foot for use more especially in work on heavy or relatively heavy pile fabrics, for example those which are used in rugs and carpets where the pile is cut, ,body Brussels, fabrics, plushes, and chenilles.

. The principal objects of the present in-' vention are to provide a simply constructed, strong and inexpensive presser foot for use on fabrics of the character stated by means of which a line .of stitching maybe formed acrossthe pile surface without any marring of such surface and without the objection.- able scoreor streak, which is produced by the ordinary methods of scam stitching.

Ordinarily, where pile fabrics are stitched across their-pile surfaces the threads catch the adjoining piles andhold .them down against the warp or backing, thus producing. anwunsightly streak across .the pile surface which detracts from the appearance:.of the manufactured article and of course-reduces its commercial value. This defect is overcome by the presser foot of the present invention which, for the avoidance of such defect, is provided with means for separating or spreading the adjoining lines of pile in advance of the needle in order that the piles may not be caught by the stitching and held against the warp or backing. In this way the stitching is directly upon the warp or backing and not upon the piles and the latter, after the passage of the needle thereby, spring back to their normal relation and conceal not only the stitching itself but also any suggestion thereof.

While the improved presser foot is capa-' ble of general application upon pile fabrics of" various kinds, its utility will probably have greatest value in the manufacture of.

rugs, which are hemmed and stitched along their edges.

An embodiment of the invention is illustrated in the accompanying drawings, wherein p Fi re 1 is a perspective view of a presser foot in which the features of the invention are incorporated. Fig. 2 is a bottom plan PRESSER-FOOT.

view thereof. Fig. 3 is a. side elevation thereof, and Fig. 4 is a front elevation thereof, showing also a sectionof pile fabric to which the presser foot is related, as in use.-

. Similar characters of reference designate corresponding parts throughout the several V16WS- l y The, presser foot shown is especially adaptedfor use in the manufacture of rugs and is disclosed merely as an example of a useful application of the invention.

. The presser foot ,is provided witha rela tively flat smooth surfaced presser portion 1 having a suitably located needle openin '2, arranged near the forward end thereo The essential characteristic of a-' presser foot inaccordance with the present inven tion istheprovision of meansfor dividing 76 needle whereby the stitching will be directly against the warp or backing and, will-mot catch the piles, and the means suggested in thedrawing for effecting this operation is a plow or plow like extension 3 which pro- 80 jects forwardly from the presser portion 1 in line with the needle opening 2. The plow Bhadjoins and preferably extends under the under face of the resser portion 1 and is preferably rigid with said presser portion, for example, by being made integral therewith. It is also preferred that the-plow 3 should extend rearwardly as far as the needle opening 2. Thus the said needle opening is formed partly in the presser portion 1 and partly in the rear portion of the plow 3. V

The plow 3 is preferably formed, as shown, with its sides tapering forwardly to provide a bluntly pointed end and with its 96 under face blunt to avoid cutting the fabric operated upon by the presser foot and inclined at a slight angle forwardly and upwardly in order that the said pointed end may be suitably elevated above the warp or backing to avoid catching against the threads thereof.

The operation will be readily apparent from the foregoing description. The plow 3 divides the parallel rows of pile in line with the stitching and in advance of the needle in such manner that the stitching is directly against the Warp or backing and does not catch the piles. When the fabric passes by the needle, the piles previously dlvided 110 or spread apart by the plow 3 spring back to their normal positions in which they conceal the line of stitching as well as any suggestion thereof. In this way a line of stitching may be formed across a pile surface without the unsightly streak which is commonly found and without any detrimental effect whatever on the appearance of said surface.

The presser foot may be secured to the presser bar in any suitable manner. ordinary socket connection, as 4, is shown in the drawings. 7

Having fully described my invention, I claim:

l. A presser foot for use on pile fabric having a presser portion provided will a needle opening and having a plow located in advance of said needle opening with its under surface in a plane below theworking surface of said presser portion, the plow being arranged to work above the plane of the warp or backing for dividing the pile in advance of and in line with the needle opening and having its said under surface blunt to avoid cutting the material of the fabric.

2. A presser foot for use on pile fabric having a presser portion provided with a needle opening and a plow arranged to work above the plane of the warp or backing and within the piles and extending forwardly from the front end of the presser portion in line with the needle opening.

3. A presser foot for use on pile fabric having a presser portion provided with aneedle opening and a plow arranged to work The above the plane of the warp or backing and within the piles and extending forwardly from the under face'of the presser portion in line with the needle opening.

4. A presser foot for use on pile fabric having a presser portion providedwith'aneedle opening and a plow arranged to work above the plane of the warp or backing and within the piles and extending forwardly from the under face of the presser portion and from the needle opening thereof.

5. A presser foot for use on pile fabric having a presser portion provided with a needle opening and a plow arranged to work above the plane of the warp or backing and within the piles and extending forwardly from the under face of the presser portion in line with the needle opening, the plow having its under face inclined at a slight angle forwardly and upwardly. T

6. A presser foot for use on pile fabric having a presser portion provided with a needle opening and a plow integral with said presser portion arranged to work above the plane of the warp or backing and within the piles and extending forwardly from the front end of the under face of the presser portion in line with the needle opening.

In testimony whereof I havehereunto set .my hand, in presence of two subscribing witnesses. 7
